I seem to have made a new mistake (node:13414) UnhandledPromiseRejectionWarning: ReferenceError: og is not defined

`/**

• Example demonstrating how to add DID with the role of Trust Anchor as Steward.
• Uses seed to obtain Steward's DID which already exists on the ledger.
• Then it generates new DID/Verkey pair for Trust Anchor.
• Using Steward's DID, NYM transaction request is built to add Trust Anchor's DID and Verkey
• on the ledger with the role of Trust Anchor.
• Once the NYM is successfully written on the ledger, it generates new DID/Verkey pair that represents
• a client, which are used to create GET_NYM request to query the ledger and confirm Trust Anchor's Verkey.
• For the sake of simplicity, a single wallet is used. In the real world scenario, three different wallets

• would be used and DIDs would be exchanged using some channel of communication */

Ha ha ha, I am so stupid to make such a mistake
